My invention relates to an alarm device, and more particularly to atelephone alarm device arranged for use with any suitable automatictelephone system.- 1

a In the various types of automatic telephone systems, a transmitter isprovided together with a telephone box containing the operatingmechanism :for completing a call to a central station,

the call being transmitted by the manipulation of the usual dial wherebyimpulses in any selected sequence within the limits of the system may betransmitted to suitable selectors also forming a part of the, system forcompleting a connection to a desired station. The transmitter, telephonebox, and dialing mechanism, together with the selectors, form a part ofsubstantially all automatic telephone systems. This invention providesan efficient means for automatically controlling the operation of thedialing mechanism to cause a predetermined sequ'enceof impulses to betransmitted to the selectors of the automatic telephone system and tocause any desired predetermined call to be transmitted to the selectedstation as soon as the connection thereto has been completed.

In this invention the operation of an automatic dialing and transmittingmechanism is arranged to be controlledby suitable automatic or manuallyoperable means or both. This control may be accomplished by means of oneor more remotely positioned thermostats operating at desiredtemperatures to control a suitable mechanical or electrical device forcausing the dialing mechanism to be operated to transmit the neces- 35sary sequence oi impulses to complete a corresponding stationconnection.

It will be understood that suitable fusible link switches may be used inplace of the thermostat,

or a combination of temperature and manually l0 controlled means may beused if desired.

It should also be understood that the term' dialing mechanism as used inthis application is intended to refer to any suitable sending meanssimilar to that usually controlled by the manually operable dial of anautomatic tdephone system. In practicing the pment invention the dialmay be omitted if desired,

It is, therefore, an object of the present invention to provide anautomatic means cooperating with the dialing mechanism and theinansmitter oi'van automatic telephone system whereby a desired stationconnectionmay be completed and a predetermined call automaticallytransmitted and wherein the operation of the automatic 5 mechanism "maybe controlled by the pelation of a temperature control device or :bymanually controlled means, or a combination of both. Also a plurality ofeither temperature controlled or manually operated devices may be usedif desired whereby the automatic dialing mechanism may becontrolled fromvarious remote points.

This invention also contemplates a simple and eflicient device wherebyany one of a plurality of predetermined signals may be transmitted toany one of a plurality of selected stations, and whereby the device maybe automatically or manually controlled from a plurality of remotepoints.

The device'is also adapted to be successfully operated from any suitableelectrical or mechanical burglar or fire-alarm system in common use atthe present time.

A further desirable feature is the provision of interchangeable meanswhereby any desired predetermined call maybe transmitted to anypredetermined station, and the further provision of interchangeablemeans whereby any desired predetermined station connection may be madewithin the limits of the telephone system, and wherein the device may beadapted for making a single predetermined station selection and call, or,for selecting any one predetermined selection from a plurality ofstation connections and simultaneously selecting a predetermined callfor the particular station connection.

A further object ofthe present invention is to provide a simple andeificient automatic alarm system for the operation of the dialingmechanism and the transmission of selected calls to selected stationswhich will be efficient in use, simple in operation and which will noteasily get out of order.

, Further objects will be apparent from the specification and theappended claims.

Referring to the drawings in detail, the embodiment illustratedcomprises a telephone box 1 which contains the usual equipment andmechanism for control and operation of the usual automatic dialtelephone.

A dial 2 is rotatably mountedon the box 1 and is of a type similar tothat used in substantially an automatic telephone systems, and may bemanually operated if desired to obtain a desired station selection.However, this dial is unnecessary for the successful operation of thepresent invention.

Apost3issecuredtothedial2ormaybe secured to or form a part of anysuitable element of the dialing mechanism whereby it may be rotated foroperation in the well known manner of dial telephones. This post in thepresent instance is square in cross section and comprises an enlargedportion 4 and a reduced portion 5.

The device for automatically controlling the operation of the dialmechanism includes a mechanism somewhat similar to the usual phonographmotor and'comprises a spring drum 6 having the usual spring or otherdriving means therein, and mounted on a driven shaft '7 which is, inturn, rotatably supported between upper and lower frame members 8 and 9,respectively, the lower frame member 9 being supported on the box 1.

The motor is provided with the usual governor mechanism which is drivenfrom a gear 10 secured to the shaft 7 and connected in driving relationwith a governor 11 by means of a train of gears comprising a pinion 12and a gear 13 on a vertical shaft 14, a pinion 15 and a spiral gear 16on a vertical shaft 17, the pinion 15 being in mesh with the gear 13 andthe spiral gear 16 being in mesh with a corresponding spiral gear 18 onthe governor 11.

The usual winding arrangement is provided for the motor spring andcomprises a worm gear 19 on the shaft 7 and a worm 20, which. latter isarranged to be operated by means of the usual removable windingcrank.

A solenoid A is mounted on the lower frame member 9 and is provided witha movable core 21. This core is arranged to be engaged in a notch 22 ina disk 23, which latter is secured to and rotates with the governor 11.The disk 23 may be the usual governor brake disk if desired or aseparate disk may be mounted on the governor shaft. The engagement ofthe solenoid armature 21 in notch 22 normally prevents the operation ofthe motor but it will be obvious that if the solenoid A is energized thearmature 21 will be withdrawn from the notch 22 and the governor 11 willbe allowed to rotate and thereby allow the continuo operation of themotor, until the armature 21 is manually readjusted in tile notch 22 ofthe governor disk. It will be understood that it is only necessary tomomentarily energize the solenoid A. Y

A spring 24 is arranged to normally rest on the armature 21 and toengage the shoulder 25 thereof when the armature is drawn out of thenotch 22, thereby preventing the re-engagementof the tatable therewithand which is similar to the usual rotating phonograph-record table.

A record 27 is supported on the table and suitable calls are recordedthereon for transmission through the, telephone system by means of atransmitter 28, which latter is provided with the usual phonographneedle 29, the needle may be secured to the diaphragm of the transmitterin the usual well-known manner of phonograph reproducers. Thistransmitter is mounted on a swinging arm 30 which forms a part of atubular post 31 mounted on the telephone box 1. Suitable conductors maybe arranged within the arm 30 and the post 31 and connected to thetransmitter of the telephone system in the usual manner.

Inthe present instance, the record 2'? is provided with two grooves 32and 33 which may have recorded therein certain predetermined calls, forinstance, a fire-call and a police-call, respectively. These specificcalls are intended as illustrative only and it will be understood thatany suitable calls may be recorded in the respective grooves.

It will be understood from the previous description that when thestarting solenoid A is energized the motor will operate to rotate thetable 26 and the record thereon, and if the dial 2 has previously or maybe simultaneously operated to complete the necessary connections in theautomatic telephone system to certain predetermined stations, therotation of the record will'cause a call to be continuously transmittedthrough the transmitter 7, the call corresponding to the recorded callin the groove in which the needle 29 is located at the time of theoperation of the device. I

The gear 10 of the motor is secured to the motor spring and rotatablymounted on the shaft 7 and provided with an enlarged hub 34 on whichinterrupted gears 35 and 36 are removably and interchangeably mounted.These interrupted gears are held in spaced relation by means of aspacing ring 36 and are secured to the gear 10 by means of screws 38.The interrupted gears 35 and 36 comprise rings which are interchangeableand any desired arrangement of spaced sets of teeth may be providedthereon, the arrangement of teeth on each gear corresponding to apredeter- .mined call which is to be made by a partial rotation of thedialing mechanism by each' set of teeth on the particular interruptedgear.

In order to operate the dialing mechanism from these interrupted gears,pinions 39 and 40 are slidably mounted on the enlarged and reducedsquare portions 4 and 5, respectively, of the post 3. These pinions 39and 40 are provided with flanges 41 and 42, respectively.

Whenthe device is at rest, a flange 42 of the pinion 40 normally restsupon a pawl 43 of an arm 44 which latter is pivoted on a post 45 on thetelephone box, thereby supporting the pinion in alignment with theinterrupted gear 35 and in" a position to be enga ed by the teeththereof when the motor is operated. In a similar manner, pinion 39 isheld in a raised position to be engaged by the teeth on the interruptedgear 36. by means of an arm 46 which latter engages underneath theflange 41 of the pinion 39. The lever 46 is also pivoted on the post 45.Magnets IB and C are mounted on a bracket 47 in a position to move thearms 44 and 46, respectively, that is. when the magnet 13 is energized,the arm 44 will be moved outwardly to release the pinion .40 which willthen drop downwardly out of alignment with the gear 35 and the dial] mayoutwardly to release the pinion 35 which will drop downwardly on thepost 3 and out of alignment with the interrupted gear 36 and the dialmay then be operated through the interrupted gear and its related pinion40 on the post 3. By this means, either of the interrupted gears may bensedtooperatethe dial totransmitacallwhich is predetermined by theenergizing of either the magnet B or C as desired.

The pinion retaining arm 44 is pivoted on the post 45 by means of anupwardly extending sleeve 48 which is provided at its upper end with aninwardly extending arm 49 which latter extends under the tubular arm 30'of the transmitter and is provided with a pin 50 arranged to engage thearm and move the transmitter and thereby the needle 29 from the innergroove 33 to the outer groove 32. This movement of the transmitteroccurs when the magnet B is energized to release pinion 40 in order thatthe rotation of the record may transmit a call corresponding to thestation selected through operation of pinion-39.

The interrupted gears 35 and 36 are provided with downwardly extendingpins 51 and 52, respectively, and as soon as the dialing mechanism hasbeen operated to send the desired sequence of impulses to the selectorsof the automatic telephone system to make the desired stationconnection, which is accomplished during a single revolution of theinterrupted gear, the pin 52 on the interrupted gear 36 will engage theinwardly extending end of the arm 46 and the arm will he forcedoutwardly, thereby releasing the pinion 39 which latter will dropdownwardly out of alignment with its corresponding interrupted gear.

The selected station connection having been made, the record 27 willcontinue to be rotated and the call from the record groove 32 will hecontinuously transmitted until the device is reset. If, instead ofenergizing the magnet B, the magnet C is energized with the parts in theset position shown, the arm 46 will be moved outwardly thereby releasingthe pinion-39 which will drop downwardly out of alignment with itscorresponding interrupted gear and the dialing mechanism will then beoperated through the interrupted gear 35 and the pinion 40. Thetransmitter will not he moved and the needlewill remain in the groove33, as in Figure 1, and will transmit the call therefrom. After onerevolution of the interrupted gear 35, the pin 51 thereon will engagethe inwardly extending end of the spring retained pawl 43 on the arm 44,the pawl will therefore be moved outwardly without moving the arm 44 andthe pinion 40 will be released to prevent further opera? tion of thedialingmechanism and the transmitter 28 will then continue to transmitthe call from the record groove 33 during the further continuousmovement of the record 2 'Z.

It will be understood that the motorcontrolling solenoid A may beenergized simultaneously with either one or the other of the magnets Bor C in order that the motor may start simultaneously with the dropp ofone or the other of the pinions 39 or 40 out of alignment with itscorresponding interrupted gear.

Any suitable means may be used for energizing the solenoid A and themagnets B and C, a suitable wiring diagram being illustrated in Fig. 5

- in which means is provided for'either automatic or manual control ofthe device; This circuit includes a plurality of remotely positionedthermomostat switches 53.
